1995 Other GMC Models 6 cyl Two Wheel Drive Automatic 140, 00 miles
i have a 1995 gmc g30 van with diesel motor. It has 140k, and runs and drives fine. I just purchased it at an estate sale. When I got it, the fuel gauge is pegged past full. Oil pressure at 0. Temp is redlined. Battery at 0. Where to start looking? Grounds? Fuses? New cluster? I am handy with meter, just need advice in which direction to go. Thanks
Start with the fuses, then check the plug in harness to the rear of the dash panel. It plugs into the rear of the panel, and will sometimes pull out a little on one side. You can also check each pin in the harness for power if you unplug it, it could be the circuit board.
